g LUBRICATING DEVICE FOR WHEELS.

SLPECIFICATION forming part of Letters Patent No. 293,070, dated .February 5,` 1884. Application filed December 14, 1883. (No model.)

To all whom it may concern:

Be it known that I, GEORGE Pnxcocx, "a citizen of the United States, residing at Selina, in the county of Dallas and State ofAlabama, have invented certain new and useful Improvements in Lubricating Devices for Wheels, of which the following is a .specificatioinreference being had therein to the accompanying drawings.

My invention relates to lubricating devices for wheels, drums, or pulleys, butV will be herein described with reference to its construction anduse in wheels. The object I have-in view is to provide an oil-reservoir around or in connection with the box or hub, which shall automatically pay out the oilV to the axlein suitable quantities, and shall at the saine time be closed in such manner as toentirely preclude the possibility of leakage after the oil has once been placed in it.

In the accompanying drawings, making part of this specification, Figure 1 represents a side view of a wheel with box introduced. Fig. 2 is a longitudinal section of the box, showing its internal construction. Fig. 3 is a plan view of' the cap or top to the oil-reservoir; and

Figzft is a perspective of a plug that closes the orifice, with key for operating it.

In the figures, A represents a wheel, which is made of cast metal-hub, spokes, rim, and all-in,` one piece. The hub consists of' a inetallic sleeve, B, for receiving and retaining the box C. The interior of the hub and the exterior of the box are made tapering. The box fitting within the hub is held in place by a series of bolts, which pass through openings,

partially in the hub and partially` in the box acting like keys, but drawing the parts together by nuts on their ends. The box Chas cast within it an annular reservoir, D, which has a longitudinal opening cut in its upper side, said opening being covered by a removable top K.

J represents a screw, which fastens the top in place, the sides of the head of said screw` resting upon a soft-metal packing to prevent leakage.

E represents a short hollow barrel, which is provided with a flange, F, a spline, H, an

" orifice, L, above the flange, and at" its bottom a stein, G. The upper end of the barrelE extends through an opening in the top or cover K, and the spline H is allowed to play in a slot, x, in one side of said opening when the barrel nioves up or down. Vhen the barrel has been pressed downward as far as it will go and is partially revolved, the spline H, having passed below its slot, catches against the under side of the cover K and holds it down. The stem G enters between the coils of a spiral spring, a, which is placed under it, said spring serving to actuate the barrel outward when free.` rIhe flange F has its upper side provided with a suitable packing or gasket, and when the barrel is freed and the spring presses it upward, the flange, with its packing, acts as a valve to shut off the escape of oil from the reservoir. The oil passes down through the barrel, and thence, when it is pressed down, thrpugh the orifice L into the reservoir. The mouth of the barrel is made square inside, so that it can be operated by a wrench constructed as represented by I.

e e represent oil-cups, which are situated in reservoir D, and over small openings which lead from said reservoir to the axle of' the wheel. Theinouths of these cups reach almost to the under side of the cover K, the cups being filled with wool or cotton or other suitable fibrous material for the purpose of conveying the oil slowly, and in small quantities but regularly, to the axle.

Vhen the wheel is running, it causes an agitation of the oil, so as always to keep the packing in the cups properly supplied. l

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, isi l. The box C of ahub, cast with an annular oil-reservoir within it, the said reservoir being provided with cups having ducts at their bottoms, through which the oil is conveyed to the axle, in combination with the removable top, the whole arranged substantially as and for the purposes specied.` l

2. The combination, with the hub having an annular reservoir, D, of the hollow barrel an orifice, L, aboverv the flange, and at its bottom with a stem, G, setting in the upper end of a spiral spring, a, substantially as and for the purposes specified.

3. In combination with tho oil-reservoir in the box, a hollow barrel, E, having a spline, H, a feeding-orifice, L, and a packed Valve, F, the barrel being actuated longitudinally and outward by means of a suitable spring, substantially as described. t

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE IEACOOK.
